So out of curiosity, I decided to visit the EarthGate in Sagan’s Lights. Not easy to get to - it’s almost entirely surrounded by nasty nebulae, and an authority ship fired on me too. However, I managed to dock on it. That’s where my problem starts: if I undock, it crashes to desktop. If I try to use my own jumpdrive to jump away, it crashes to desktop. I think I’m irrevocably stuck.
One thing I noticed is that while docked to EarthGate, both of my airlock doors are open, even though it is space outside, and the door buttons don’t work.
So, learn from my mistake - don’t visit the EarthGate.
